Intravesical migration of an intrauterine contraceptive device complicated by bladder stone: a report of six cases.

Intrauterine contraceptive device is the most popular method of reversible contraception in developing countries due to its efficiency and low cost. However, this device is often inserted by paramedics of variable skills, and follow-up evaluations are irregular or absent which can be the source of major complications. The authors report six cases of intravesical migration of intrauterine contraceptive devices complicated by bladder stones. All the six cases were managed endoscopically with excellent outcome. The authors demonstrate that this major complication can be managed endoscopically with decreased morbidity for the patient.

Colonic perforation complicating percutaneous nephrolithotomy.

A case of colonic perforation complicating percutaneous nephrolithotomy in a 64-year-old woman is reported. Nonoperative management was successful with the creation of a controlled colocutaneous fistula by pulling the nephrostomy tube back from the kidney to the colon and the use of an elemental diet and antibiotics. Internal urinary drainage was not necessary.

Adrenal cystic phaeochromocytoma: a case report.

Cystic phaeochromocytoma is a rare occurrence. We report a case of a 42-year-old woman who presented with the cardinal symptoms of phaeochromocytoma with elevated serum catecholamine levels. Radiological investigations showed a cystic mass in the right adrenal. Right adrenalectomy through a subcosal incision was performed and pathological examination concluded to a cystic phaeochromocytoma. We discuss the pathophysiology of such cyst formation as well as differential diagnoses.

[Idiopathic renal vein thrombosis. About two cases].

Renal vein thrombosis is a rare pathology difficult to diagnose. It has quite various clinical expressions and biological consequences. The diagnosis is based upon radiologic explorations. This entity may have various causes. Detecting this condition may lead to restoration of renal function compromised by renal vein thrombosis. The treatment of renal vein thrombosis is mainly medical and based on anticoagulants. The role of fibrinolytic treatment is controversial. Surgery is exceptional. We report two cases of idiopathic thrombosis of the renal vein in adult patient. Also, we have done a review of the literature on this clinical syndrome and its diagnostic and therapeutic aspects.

Vesicouterine fistula as a complication of forceps delivery: a case report.

We report a case of vesicouterine fistula as a complication of forceps delivery revealed by urinary incontinence in a 68-year-old woman. Diagnosis was confirmed by examination and cystography. The treatment was a transperitoneal excision of the fistula. The literature is briefly reviewed and the treatment options are discussed.

Intravesical hydatid cyst.

A case of intravesical hydatid cyst is reported. The cyst was completely evacuated cystoscopically with intravesical instillation of a scolicidal agent (hydrogen peroxide) to destroy scolices and daughter cysts. The postoperative course was uneventful, and follow-up did not show evidence of recurrence. Because this is the first case, to our knowledge, to be reported, little is known about the nonoperative management of such hydatid localization. A recommendation is made, however, to adopt this minimally invasive procedure.

[Vesico-sigmoid fistula secondary to diverticulitis: a case report].

Vesico-sigmoid fistula is a rare complication of colic diverticular disease. It develops when the bladder sticks to an inflammatory colon making of a communication between the bladder and the digestive segment, usually the sigmoid. Liquid usually passes from the colon to the bladder because of the existing pressure gradient. Hence, urinary symptoms are the most frequent. Surgery is the treatment of choice. The present case is about a 72-year-old man who had a total hematuria for 3 months. The diagnosis of a vesico-sigmoid fistula secondary to colic diverticulitis was established by cystoscopy, colonoscopy and cystography. Surgery was underlaken and the postoperative outcome was excellent. Through this case the clinical features, special investigations and treatment of vesico-sigmoid fistula, are reported.

[Transrectal ultrasound in the diagnosis of prostate cancer].

Transrectal ultrasound is an important tool in detection and management of prostate cancer. Its role is to identify and characterize focal lesions before capsular invasion and metastases and to guide biopsy of the prostate. In this paper, we present a overview of the state of trans-rectal ultrasound imaging in prostate cancer.

Laparoscopic retroperitoneal ureterolithotomy: initial experience and review of literature.

PURPOSE: To evaluate the place of retroperitoneal laparoscopic ureterolithotomy in the management of ureteral calculi through an initial experience and review of previously reported cases. PATIENTS AND METHODS: Laparoscopic ureterolithotomy was attempted in six patients (five men and one woman) with an age of 31 to 56 years (mean 41.5 years) who had large and impacted stones in the upper ureter. The stone size ranged from 18 to 40 mm (mean 25.7 mm). The retroperitoneal route was used in all cases. RESULTS: The stone was removed in all but one case. The operative time ranged from 120 to 180 minutes (mean 160 minutes). No intraoperative complications were encountered. Postoperative complications included prolonged urinary leak in one patient. On follow-up, all patients were stone free with decompression of the upper urinary tract. CONCLUSIONS: Laparoscopic ureterolithotomy is safe and effective and should be performed each time a ureterolithotomy is indicated.

How to insert a double J stent in laparoscopic retroperitoneal dismembered pyeloplasty: a new technique.

Antegrade placement of double J stent during laparoscopic pyeloplasty is technically demanding and time consuming, especially when operating in the retroperitoneal space. We report a new, time-saving method to antegrade insertion of a double J stent that we use in retroperitoneal laparoscopic dismembered pyeloplasty. This technique employs the recovery of a guidewire introduced retrograde through an open tip ureteral catheter placed in the mid-ureter at the beginning of the procedure and brought into the sterile area. The guidewire issued through a laparoscopic port will be used in the antegrade insertion of the double J stent. We used this technique in 6 consecutive retroperitoneal laparoscopic dismembered pyeloplasties. The stent was correctly placed in all 6 cases in less than 5 minutes without any difficulty. This is a simple and straightforward technique.

[Retroperitoneal paraganglioma: case report].

Paraganglioma are rare neoplasms arising from undifferentiated cells of the primitive neural crest. We report a case of a 53 years old patient presented with a large tissular retropéritoneal tumour situated above the left kidney. Serum Adrenaline, Nor drenaline and VMA levels were normal. Surgical complete resection of the tumour was performed without intra-operative incident. The histopathological examination and the immunohistochemical analyses concluded to a non secreting retroperitoneal paraganglioma. Postoperative course was uneventful.

How did the endoscopic video camera change our practice in transurethral resection of the prostate? A retrospective study of 200 cases.

PURPOSE: Video camera-assisted transurethral resection of the prostate (TURP) is an invaluable teaching tool and provides physical comfort to the surgeon. However, whether it improves technical skills and reduces complications rates and hospital stay has not been well documented. PATIENTS AND METHODS: We retrospectively reviewed 100 cases of video camera-assisted (VCA) TURP and 100 cases of non-video camera-assisted (NVCA) TURP randomly chosen from 1490 cases performed over a 5-year period. The patients' mean age was similar in the two groups (70 years in the NVCA group and 71 years in the VCA group). RESULTS: The mean weight of prostatic chips was 33.2 g in the VCA and 19.02 g in the NVCA group (P < 0.05). The mean operative time was identical in the two groups (VCA 41 minutes and NVCA 42.2 minutes). The mean postoperative hospital stay was shorter in the VCA group than in the NVCA group (1.56 and 3.39 days, respectively) (P < 0.05), as was the urinary drainage time (1.68 and 4.04 days, respectively) (P < 0.05). In the NVCA group, three patients had profuse hemorrhage necessitating blood transfusions and two had TURP syndrome, while in the VCA group, one patient had TURP syndrome and no patient experienced intraoperative or postoperative hemorrhage. Urethral stricture was less frequent in the VCA group than in the NVCA group (1% and 3%, respectively). CONCLUSIONS: With video camera-assisted TURP, we resected larger prostate glands with minimal intraoperative bleeding, better hemostasis, and a shorter hospital stay.
